3D Sound Intensity Analysis Software
DS-0225
3D bar graph
3D mesh mapping
Sound Intensity is the acoustic energy (power) which passes through a specified area at a certain point in sound field in a specified time.
Measuring the energy in 3D achieves to presume the position of sound source, obtain amount of radiation from sound source and direction of flowing acoustic energy which is passing through the measuring surface.
The Sound Intensity Analysis Software DS-0225 consists of the “Sound Intensity Analysis Function” and “Sound Source Probing Function”. The former captures the flow of 3D sound and visualizes its directions and amount with 3D displays, and the latter is mainly used for measurement and analysis of the sound source position.
Features
*In use of 3D SI (Sound Intensity) probe (Three times of measurement in total at each point are required when using 1D SI probe.)
